Features: colonies are arborescent branches with straight tapered to form clusters. The sub-branches are provisions at an obtuse angle. The axial corallites are prominent and tubular. The radial corallites are small and curved near the tip of the branches, and become tubular moving down along the branches, where they become perpendicular, and only slightly curved. These then become prominent axial corallites with a few small corals around their base. All corals are surrounded by thick walls with rounded openings.
Color: light brown with white axial corallites.
Similar species: A. parilis and A. Exquisite, with both arms corralliti finer and smaller. (See also A. pectinatus).
Habitat: upper areas of the reef.
Distribution: usually uncommon.
